I've got some code to make a text-adventure game. I'm trying to use the Database for progress flags. this section is moving some crates to find something. if((args.move === "crates")) { // do stuff if (#db.f({_id:PlayerPATH}, {_id:0, cratemove:1}).distinct("cratemove") == "cratemove"){ return "`B***The crates are already up against the walls.***`" }else{ #db.us({_id:PlayerPATH}, { $set:{cratemove:"cratemove"} }) return "`B***You move the crates against the side walls, creating a path through the middle and exposing the ``Vfurnace``B .***`" } } The variable was originally called 'movedcrates'. I changed it as it was exhibiting odd behaviour and I wanted to test fresh. I have a dbcheck script. if(!args) { let data = #db.f().count() return data } >>dbcheck {user:"sud", path:"path"} { _id: "sudpath", movedcrates: "movedcrates", cratemove: "cratemove" } >>sud.dbcheck 3 shows that I have 3 items. I ran a delete if(args.delete === true) { return #db.r({}) } >>dbcheck {delete:true} { n: 3, opTime: { ts: "Undefined Conversion", t: 3 }, electionId: "Undefined Conversion", ok: 1, operationTime: "Undefined Conversion", "$clusterTime": { clusterTime: "Undefined Conversion", signature: { hash: "Undefined Conversion", keyId: "Undefined Conversion" } } } >>sud.dbcheck 0 tried to delete it so we're down to zero items. Then I went through the process to move the crates again, and checked my DB flags. >>sud.pathways {move:"crates"} ***You move the crates against the side walls, creating a path through the middle and exposing the furnace .*** >>dbcheck {user:"sud", path:"path"} { _id: "sudpath", movedcrates: "movedcrates", cratemove: "cratemove" } and both the old flag and the new flag were found.
